What FENESTRA Sk does

FENESTRA Sk, spol. s r.o. is a privately held Slovak manufacturer of plastic (PVC) and aluminum windows, entry doors, and sliding systems, founded in 1997 and headquartered in Zlaté Moravce. The company operates an in-house production facility there and sells custom-manufactured units through a network of sales offices, showrooms, and mobile sales representatives across Slovakia, supported by a toll-free hotline, a website quote-request form, and a consumer financing partnership with Tatra banka. Its product range spans REHAU plastic profile systems (ARTEVO composite, Synego, Euro-Design 70), aluminum systems from Schüco and Aluprof, sliding door variants, panoramic doors, and Aluprof fire-rated systems (MB-60E EI, MB-78EI, MB-86EI), with installation and post-warranty service bundled in.

The business model is quote-based, per-unit pricing with installation services included and after-sales support offered. Customer segmentation is hybrid: primary volume comes from individual residential homeowners replacing or installing windows and doors (with point-of-sale financing available via Tatra banka at 4.99–5.99% APR over 6–96 months), while a secondary stream targets commercial and institutional projects — offices, hotels, shopping centers, and universities — with a reference portfolio that includes DoubleTree Hilton Bratislava, SPP headquarters, Perla Ružinova (4,971 units), and University of Comenius Science Park (~11,000 m² facade). The company holds ISO 9001, ISO 14001, and ISO 45001 certifications, operates solely within Slovakia, and has recently secured EU grants for photovoltaic installation at the production facility and employee skills development. In 2024, FENESTRA Sk became the first to introduce the REHAU ARTEVO composite window system to the Slovak market; that product has received the German Design Award 2024 and Iconic Award 2024 Best of the Best.

Direct peers

• DAKO: Czech manufacturer of plastic and wooden windows and doors with similar tier and product breadth serving the Central European market. Closely comparable in scale, channel mix, and customer profile to FENESTRA Sk.
• RI OKNA: Czech producer of plastic, aluminum, and wooden windows for residential and commercial markets. Operates with similar sales-led model and product breadth to FENESTRA Sk, and serves the same Central European geography.
• Internorm Fenster: Austrian premium manufacturer of plastic-aluminum composite, timber-aluminum, and aluminum windows and doors. Operates in the same premium European window/door segment as FENESTRA's ARTEVO and aluminum offerings, with deeper adjacent geographic coverage.

Broad incumbents

• Hörmann: German global leader in building envelopes, doors, and industrial access systems. Substantially larger than FENESTRA Sk and offers overlapping fire-rated entrance door systems but in a much wider portfolio; competes on commercial projects.
• VELUX Group: Danish global leader in roof windows and skylights. Vastly larger scale and an adjacent rather than directly overlapping category, but competes with FENESTRA in premium daylighting and energy-efficient building envelope specifications.
• Reynaers Aluminium: Belgian manufacturer of aluminum windows, doors, sliding systems, and facades for commercial and high-end residential projects. Comparable to FENESTRA's Schüco/Aluprof aluminum offering but at substantially larger European scale.

Regional players

Others

• VEKA AG: German PVC profile and finished-systems supplier that competes indirectly with FENESTRA Sk via licensees and direct sales subsidiaries. Functions as supplier and indirect competitor in the same PVC window value chain.
• Gealan Fenster-Systeme: German PVC profile manufacturer (part of VEKA Group) serving window fabricators across Europe. Comparable upstream supplier position to REHAU in FENESTRA's profile procurement, and an indirect competitor to fabricator customers.
• Salamander Industrie-Produkte: German profile manufacturer producing Salamander window and door systems for European fabricators. Comparable upstream supplier role to FENESTRA's REHAU/Schüco/Aluprof relationships, with limited direct overlap in finished products.
